The IDsCaptureDriverBufferinterface is used to manipulate individual sound capture buffers, which are separate objects from the main driver object (which supports IDsCaptureDriver). The IDsCaptureDriver::CreateCaptureBuffermethod creates a sound capture buffer object and returns an IDsCaptureDriverBufferinterface.

The IDsCaptureDriverBufferinterface contains the following methods:
